Great thread still very useful, especially the point about testing the SQL first and then moving it into Power BI. That workflow saves a lot of time when you’re debugging filters, date conversions, or reserved column names.

I also like the focus on keeping queries clean when working with live data sources. Even small changes in query structure can make a big difference in performance and reliability once the report starts growing.

For teams that need more advanced reporting setup (data modeling, dashboard architecture, refresh optimization, etc.), it can also help to hire power bi developer instead of trying to solve every issue ad hoc.
